Taking note of the equilibrium

4HCl(g) + O2(g) ----> 2H2(g) + 2Cl2(g).

What would be the the equilibrium law expression for the balanced chemical equation?

  • chemistry -

    Remember that Keq = the product of the products of the reaction divided by the product of the reactants, each raised to a power indicated by the coefficient in the balance chemical equation.

  • chemistry -

    My best answer would be:
    HCl]4[O2] / [H2O]2[Cl2]2

    Is this correct?

  • chemistry -

    No. See my response to your repost above.
    H2 and Cl2 are the products of the reaction. Right? and where did the H2O come from? That isn't anywhere in the equation.
